The willingness to pay-willingness to accept gap: a failed replication of Plott and Zeiler

[Arbeitspapier]

We report on experiments to replicate Plott and Zeiler's (2005) findings that the WTP-WTA gap disappears when using procedures that are aimed at reducing misunderstandings, such as training rounds for the BDM mechanism.

We report on experiments to replicate Plott and Zeiler's (2005) findings that the WTP-WTA gap disappears when using procedures that are aimed at reducing misunderstandings, such as training rounds for the BDM mechanism. Following the design by Plott and Zeiler (2005) and Isoni, Loomes, and Sugden (2011) who re-ran the Plott/Zeiler experiments to study the paid practice rounds with lotteries, we replicate the findings from the lottery tasks where a WTP-WTA gap is present in all studies. However, unlike in the two previous studies the WTP-WTA gap does not disappear in the main task where subjects state their WTA or WTP for a mug. We introduce two additional lottery tasks to classify subjects and find that even for the most rational group of subjects who never make dominated choices in the paid practice rounds, the WTP-WTA gap in the mug task exists. The findings are replicated in a similar experiment with USB sticks instead of mugs. (author's abstract)... weniger
